TxtToSeq: Transform Text into Sequences Fast
TxtToSeq is a lightweight utility (library/CLI/service — assume library) that converts raw text into structured sequences suitable for downstream tasks like NLP model input, time-series alignment, or data pipelines. It focuses on speed, minimal configuration, and predictable, reproducible outputs.
Key features
- Tokenization: Fast, configurable tokenizers (whitespace, regex, subword/BPE-compatible hooks).
- Normalization: Lowercasing, Unicode normalization, punctuation trimming, and optional stopword removal.
- Sequencing: Fixed-length and variable-length sequence generation with padding, truncation, and sliding-window support.
- Encoding: Support for integer ID mapping, one-hot vectors, and sparse representations for large vocabularies.
- Batching & Streaming: Efficient batching and streaming modes for processing large corpora without high memory usage.
- Preservation of metadata: Optionally attach offsets, sentence/paragraph indices, and original-text pointers for traceability.
- Extensible hooks: Pre- and post-processing hooks for custom filters, embeddings lookup, or feature extraction.
Typical workflow
- Input raw text (string, file, or stream).
- Normalize and clean text (lowercase, remove control chars).
- Tokenize according to chosen tokenizer.
- Map tokens to IDs or vectors.
- Generate sequences (pad/truncate or slide) and batch for model input.
- Optionally emit metadata mapping sequences back to source text.
Performance & scalability
- Optimized for CPU with vectorized operations and optional multithreading.
- Streaming mode avoids loading entire datasets into memory.
- Designed to integrate with model-serving pipelines and data-prep jobs.
Use cases
- Preparing inputs for language models and sequence classifiers.
- Converting transcripts or logs into time-aligned sequences.
- Feature generation for ML pipelines needing fixed-length inputs.
- Rapid prototyping of tokenization and encoding strategies.
Example (pseudocode)
pipeline = TxtToSeq(config)seqs = pipeline.from_text(“This is an example sentence.”)seqs.pad(length=16)batch = seqs.to_batch()
When to choose TxtToSeq
- You need fast, reproducible conversion of text into model-ready sequences with low setup overhead.
- You want easy integration with streaming data or large datasets.
- You prefer an extensible toolkit with hooks for custom processing.
If you want, I can: provide a concrete code example in Python, suggest tokenizer choices, or design a pipeline tuned for a specific model (specify the model).
